			<p>The following equations are represented in the HTML source code as LaTeX expressions.</p>
			<h1>The Cauchy-Schwarz Inequality</h1>
			<p><span class="math-tex">\( \left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right) \)</span></p>
			<h1>The probability of getting <span class="math-tex">\(k\)</span> heads when flipping <span class="math-tex">\(n\)</span> coins is</h1>
			<p><span class="math-tex">\(P(E) = {n \choose k} p^k (1-p)^{ n-k} \)</span></p>
			<p>Finally, while displaying equations is useful for demonstration purposes, the ability to mix math and text in a paragraph is also important. This expression <span class="math-tex">\(\sqrt{3x-1}+(1+x)^2\)</span> is an example of an inline equation. As you see, MathJax equations can be used this way as well, without disturbing the spacing between the lines.</p>
